This I what I mean:1. I open the editor2. Make the changes. It saves automatically3. I leave the window4. After 10 seconds "The document editing service informs the document storage service about status of the document editing using the callbackUrl from JavaScript API." https://api.onlyoffice.com/editors/callback5. In the document storage service I save the file locally

Now my question is how can I reduce the callback time from 10 seconds? Where is that value configured? What is the motivation behind the 10 seconds?

I can't seem to find the path you mentioned.I am using version 3.0.0-99 on Ubuntu 15

The only thing remotely close is /var/www/onlyoffice/documentserver/CoAuthoringService/CoAuthoring/sources/DocsCoServer.jsIn that file on line 84: var c_oAscSaveTimeOutDelay = 5000;Changing the value of this var had no effect. The callback still triggered after 10 seconds.
